Abstract (en)

Clock recovery circuit for an ATM receiver. Automatically derive the frequency of the source signal which is transmitted by the ATM cells. A subcircuit (3, 4, 5) determines, on the basis of the cell rate, the nominal bit rate of the source signal and generates a clock signal having a frequency which is consistent therewith. A second subcircuit (6, 7, 8, 9, 10) corrects, in proportion to the difference between the nominal bit rate and the mean actual bit rate, the frequency of the clock signal generated by the first subcircuit. <IMAGE>
